The .main drive Motor l is connected for continuously operating shaft 2having pulley 3 connecting drive belt a extending to pulley 5 on shaft 6(Figs. 1, 2). This shaft 6 has xed therewith pinion 7 in mesh with gear8 thereby providing continuous rotation for this gear 8. By treedie 2having dried fulcrum l() on base 11 for housing 12, there may be throughdepressing treadle 2 a pulling down of rod 13 (Fig. d) Vagainstresistance of' spring le as coasting with collar 15. This roel 113 inauch downward movement is directed by bracket ld carried by the housing12. This downward pull of the rod 13 and its head 17 to beclear of way16 thereby permits spring 18 to thrust plunger 2o axially into the seatvacated by the head 12 to connect this gear 8 to companion clutchniember or collar 21 fast on shaft 22. There is thus provided onecomplete rotation for the shaft 22 at each depression of the treadle orlever il.

This shaft 22 extends through 4the housing 12 and at its remote endcarries sprocket wheel 23 (Fig. 3) from which extends sprocket chain 24as a speed reduction to sprocket wheel 25 fast with shaft 26 in thehousingr 12 to give herein a four-to-one speed reduction ratel ofrotation for the shaft 26. it accordingly follows that at eachdepression of the treadle 2, there may be a 88' travel of the shaft 26.

Blank set-up and end sealing collapsed blank 27, (Fig. 32), as a datarticle received in compact form by the dairyinan, is opened upinto'rectangular tube (Fig. 33) by the attendant at this end sealermachine. This attendant disposes this set up tubular blank 2'? to slideupon block 28 (Figs. 1, 5), with the attendant standing at operatorsstation adjacent the treadle 9. This thrusting oi' the tubular blank onthe block 28 is with the blank extension 28 down over the tube and theblock end in position to have, as to the attendant, the position shownin Fig. 34. The attendant with this blank thrust down on the block 28,collapses similar opposing minor end flaps 30 toward each other over theblock 28, thus disposing such in proximity to the end of the block 28.The attendant in thus directing these minor flaps 30 has such in thatproximity to the block 28, that there is freedom to ride undernon-rotary bar 31 mounted in brackets 32 on the housing 12. Y

Adhesive applying deoice Fixed to rotate with the gear 8 loose on theshaft 22 is sprocket wheel 33 (Figs. 2, 4) continuously -rotatable andconnected by sprocket chain 34 with sprocket 35, fixed with gear 36 andloosely mounted on the rod or bar 31. This gear 36 is in mesh withpinion 37 (Figs. 1, 5, 6) fast o n shaft 38 carried by the brackets 32to pivot on the rod 31. These brackets 32 are connected by plate 39carrying pockets or glue pots 40 adjustable by screws 41 (Fig. 7) tovary their clearance as to adhesive or glue applying rolls 42 fast onthe shaft 38. These rolls 42 are accordingly closures for the respectiveglue pots and, as rotating relatively thereto on their surface, carry athin coat of adhesive. i

Shaft 26, as extending into the housing 12, carries fast therewith ange43 (Fig. 5) connected by bolts 44 with ilange 45 fixed with sleeve 46rotat'ably mounted on stub shaft 47 held by set screw 48 in'bracket '49fixed with the' frame or' housing 12. It is thus seen that shaft 47 isnonrotary and provides a bearing for the sleeve 46. This sleeve 46,adjacent the bracket 49, carries collar 50 held by set screw 51 againstrotation relatively to the sleeve 46. This collar 50 is accordinglyangularly adjustable relatively to the .sleeve 46 and has fast therewithcam disk 52 having seats 53 (Fig. 2). Roller 54 rides on this disk 52and is carried by extension 55 from a bracket 32. The extension 55 is ofsuch length that normally the shaft 38 is positioned as the roller 54 ison the cam 52 to hold the rolls w clear of operative position. However,as the roller 54 rides into cam depression 53, the glue carrying rollsti2 then swing radially, inward and are in operative position.

With the bloclr 22 approaching upper position, the operator may charge atubular blank 27 on. the bloei; 28 with the minor flaps 38 directed overthe end of the block 28. From this charging tion there is travel of thecarried block 28 ninety degrees (96) for this block 28 is directed byarm. 56 connected (Figs. 5, 10) by bolts 5'? to theilangeo 43, e5. 1nthis travel, wings 53 spread major dans 59, from radially extendingposition as to the shaft 23 and from parallel relation (Fig. 35i tospread relation (Fig. 36), against raised portions to (Figs. 5, 12,14)on members 61 having bearings or tubular openings 62 mounted on tubes 83anchored by nuts 6a in spiders 65, 66. The

spider 65 is connected by bolts 67 with the sleeve ed (Fig. 5). Thespider 66 is connected by set screw 88 with the shaft 26. It thusfollows that these raised pads 6b travel angularly with the shaft 26,and the block 28 and in thistravel, at the position where the disk cam52 has depression 53 register with roller 54, the glue rolls 42, bygravity, swing radially inward upon. rod 31, as an axis, to contact theflaps 59` on the radially outward side and thus coat such dem with theadhesive, due to the relative rotation of these rolls 42 as to the flaps36.

Folding The block 28 is provided with stem 69 guided in tubular arm 56(Fig. 5) and engaged by compression spring 70, the compression of whichis determined by plunger 71 as acted upon by stationary cam 72 carriedbythe non-rotary shaft 47. This stem 69 has fixed thereon collar 73against which engages compression spring 74 in open-work region of thearm 56 abuts outer terminus 75 of open-work region in the arm 56, Thisspring 74 is stronger than the spring 70 and accordingly normallyretains the block 28 retracted against the action of the cam 72, but onthe operation of the cam 72 for outward thrust, there is suchcompression of the spring 70 as will locate this block in the desiredradial position at the charging stage approximately ilush with the pads66. i

In the travel from this charging position, clockwise, (Fig. 11) cam 72has portion 76 hold the block 28 in this flush position until after thegluing means or rollers 42 have acted, then depression 77 in the cam 72allows the head or block 28 to be retracted by the spring 74 radiallyinward.

This deects slightly outwardly both of the flaps to the block 28, forthe member 61 carries pin 81 extending through slot 82 in the tube 63(Fig. 14) there to be engaged by compression spring 83 normallythrusting a roller 78 or 79 against the cam 80 effective in itscooperation with said roller, to shift the member 61.

At the gluing stage, before the head 28 has withdrawn inward, camportions 84 coact with rollers 78. 79, bringing the members 61 intoproxunity to the mank tube on the mock 2s. .Past the' gluing operation,there is relee from this held position by cam portions 85, 86. 'I'heroller 78 from cam portion 85 travels on cam portion 87 toward and undera partially raised flap 59, thus effecting folding of such flap 59 overthe pair of iiaps 30 (Fig. 9). As this operation is completed, camportion 88 retracts this folder element or support 61 and cam portion 89eoacts with roller 79 for thrusting companion member 61 toward thedepressed block 28 to fold the second ap 59 over the. rst ilap 59 inthus completing the end closing sealing operation. 1

This roller 79 in coasting with cam portion 89, holds this second, andaccordingly both of the naps 59 in the sealing position for convertingthis open end tubular blank into a one-end` sealed container.

At the peak position for the cam 87 in efecting folding of the firstflap 59, .the roller 78 as loeating the support 61 in this foldingposition, is over the block 28, and cam portion 90 (Fig. 11) of the cam72 thrusts this block 28 radially outward into compacting position, insupplementing the sealing action of the sllpPOl' 61 on the rst nap 59.Thereafter, cam portion 91 allows the block 28 to be depressed slightlyduring the period that the cam portion 88 is eective. At the region forthe cam portion 89, this cam 72 has cam portion 92 as a holding meansfor snugly compacting the pair of major naps 59 against the folded minornaps 30 in the holding sealed during the travel back toward chargingposition, where this cam portion 92 terminates in cam portion 93 inreleasing the block 28.

Eiector In the charging of the tubular blank on the block 28, the inwarddistance of the blank as to its extension 94 (Fig. 36) abut stop 95(Figs. 8, 10, 13). This stop 95 is a set screw adjusted ledge carried bycross head 96 extending into slots 97 of the spiders 65, 66. This crosshead 96 extending into slots 97 of the spiders 65, 66, terminallycarries rollers 98, which, in the region from cam portion 93, along camportion 99 (Fig. 11) of the cam 72, coact with guide 100, 101, (Figs.10, 13) fixed with the housing 12, thus moving this ledge radiallyoutward along the block 28 and thrusting the one end sealed containeroutward, radially oif the block 28, so that the operator may readilyremove upwardly such completed container and supply in its stead a tubeblank for a repetition of this cycle of operations in the four stages ofthis intermittent drive as herein, such stages being from the uppercharging 90 clockwise (Fig. 10) to the first nap sealing as a rst stage;directly in passing therefrom there is the second major ap sealing asthe second stage; and-third and fourth stages as the holding forallowing the glue or sealing means to set.

Coating mechanism The operator in taking the one-end-completed blankfrom the gluing mechanism, deposits such from the operators station nearthe treadle 9 in rectangular tubular pocket 102, open ended above andbelow. These pockets 102 are carried by endless belt 103 (Fig. 1). Eachof these pockets 102 (rms. 1, 151s) im timer iufm-mds se ated by4torsion spring 105 to limit the descent of one-end-cled blank106thereinto. This endless conveyor 103 is shown as having a drying orhardening section for the glued or just-formed container as a timeinterval. This conveyor 103, as actuated in synchronism with the endgluing mechanism for shaft 26, is connected by coupling 107 with shaft108 upon which is mounted bevel pinion 109 in mesh with bevel pinion 110on vertical shaft 111 carrying spur g'ear 112 in mesh with intermediategear 113 coacting with gear 114 fixed with roller 115 mounted on fixed'vertical shaft 116. This roller 115 is thev live roller for the conveyor103, which conveyor 103, from the roller 115, passes about idler roller111i7 on vertical Shaft 118.

This conveyor as conducting the containers 109 from about the roller 117(Fig. 1) for a glue hardening or seasoning operation, brings thesecon..- tainers step by step to chute 119l1aving cam edge 120 coactingwith the depending trigger 100 (in travel to the left, Fig 15) to shiftsuch clear of closure position for the botom o1 the pocket 102 as cominginto position at the chute 119. The container 106, thus drops closed enddownward through the chute 119 (Fig. 17) into open wort: pocket 121(Fig. 17) carried by arm 122 fast on the shaft 108. This device rotatesstep by step counter-clockwise in housing 123 having therebelowleakproofcoating bath chamber 12a herein shown as charged with moltenparamn 125, the molten condition of which is maintained by hot waterjacket 126 disposed in base 127 as carrying the housing 123. The arms122, besides carrying the open work pockets 121, which pockets 121 haveclosed ends 128, areprovided with arms 129 having opposite extensions130. These arms, laterally of the pockets 121, coact, from positioningthe pocket adjacent the chute 119 as held by a pin 131, to partiallytilting the pocket 121, as containing a container 106 in passing fromeach position.

Full orienting of the pocket is prevented by pin 132, so that, as thecounter-clockwise movementl of the arm 122 continues, the pocket.12l isdirected, with its closed end 128 upward, into the i therein loaded witha quantity of the paramn, 1

upward out of the bath. In this ascent, pin 13e engages the rod 130 andtilts the pocket 121 to orient the open end of the container downwardfor slopping out of the container` the scooped-up charge of the moltenparaffin, for flowing back into the bath 124. 1n this ascent, throughthe open work closed end 128 of the pocket 121, spring is eifectiveyieldably for urging this parailln dipped or leak-proof-coated container136 out of the pocket 121 upon chute 137 (Figs. 18, 19, 20, 21). Hotwater circulation pipes 138, through bearings 139 and return bend 140adjacent the chute 137 maintain a softening temperature for theleak-proofing substance, so that the coated container 136 asv strikingthe chute 137, 140, freely slides down such incline, to be depositedupon conveyor 141.

`ing has adhesive tendency and in order to avoid ilo 149 es the live ordriving pulley for conveyor 141.

This conveyor ldLremote from the pulley 14:9, passes about pulley 150corried by bracket 151 on the conveyor freine. This conveyor issoxzord-s ingly given a step hy step rotation in synchrowith the gluingmechanism as well as the costing mechenism.

Fast with the shsft 148 is gear wheel 152 in mesh with pinion 154i onsheft 155. This t 155 entends (Fig. 1) past the conveyor 1111transversely and there carries arm 156 from which entends link 157(Figs. 1, `21) to lever 158 having fixed fulcruxn 159. From this lever158 extends link i to pin 161 es directed hy centrally countersunkrhomboidol com 162. From this pin 161 is spring extension 163 inwardlyextending from beyond the link 160, duplicnte of which mechanism is onopposite sides of this upper reach of the conveyor 141.

1n the step by step rotation of the shaft 155, the pins 161 ride olongthe outer sides of cams 162. These-pins then approach each other asdirected by the inclined sides of the cam 162 towerd the shsft 1:18(Fig. 1) end cause the yield= able arms 188 (Fig. Ii0) to engage thecoated container 136 slightly above its center of grevity, ond thus inthe cycle of rotation of `this shaft 155 with the pins 161 travelingswoy from the shaft 1de along the inner portions of cams 162 anddirected by spring ngers 16d, grip this container 188 for hauling it oilthe coating machine end wiping the bottom of such container acrossscraper wire 165 (Figs. 19, 20, 40).

it the cycle of the single complete operation of the rotation of theshaft 155 in its four-to-one speed-up relatively to the sheft 108, thepins 161 come to diverging portions of the cams 162 sind are clear ofthe springs 18d, thus causing the pins 161 to move outwardly from theconveyor 141, with the yieldable arms of springs 163 releasing theset-up costed container 136 on the conveyor belt 1111. This conveyorbelt is o o length to the pulley 150 sumcient to allow the paraffincoating material to congeal. This conveyor lil in its return reach onthe under side is contacted by wire scraper 166, adjacent hot water line167 for removing any excess of the coating material so that such may bedeposited in vessel 168 therebelow Thus the conveyor belt 141 ismaintained clear of coating accumulation, so that the articles may notfreeze thereto or be tilted in the shifting of the articles thereolong.The articles accordingly as traveling along the conveyor 141 come tochute 169- and there accumulate in receptacle 170 (Fig. 1). Charging andfinal closing From drive shaft 2, pulley 171 is connected by belt 172 topulley 173 having speed reduction gearing connection 174 to gear 175 ascontinuously rotating and mounted on shaft 176 (Figs. 1, 22). At thesecond operators station, treadle 177 may be depressed to operate rod178 and thus release clutch 179 similar to the clutclr at the gear 8.This permits the gear175 to operate the shaft 176 one complete rotation.

Bottle extension closure partial collapse Mounted on this shaft 176 iscam 180 (Figs. 22, 3l). cem coects with pair of spaced bers 181 asdirected by guide 182 carried by cross bor 183 oi frame 18e, for descentagainst lthe, resistance of tension springs 195 carried from overheadher 188 mounted by the frame 184. These here 121 extend post the guide182. Extensions 157, 188, ere fixed guides for guide rod 187' fired withcross-head 189, 190 (Figs. 26, 27, 28). These hors 181 extendrespectively to links 191 connected to arms 192 of levers havingiulcre`1o3 and extensions 19d therebelow. The cross-heed 199 lies, inopposing relation pivotal mountings 195 ond upwardly extending V-tongues 19d (Fig. 29) engaged by the inwardly disposed free ends oi'thev erms 194 of ongle levers 192, 19t. These pivotally mounted,upwerdly extending. il-tongues 196 have depending lorwled lower portions197 tending normally to hold these tongues 196 in slightly divergingupward position from the pivotal mountings 195.

The operator et the station of the treadle 177 moy remove container 136from the receiver 170 and place such on platform 198 (Figs. 1, 22) inposition below the cross head 190 and abutting nger 199 on rod 200. Thedepression of the pedal or treadle 177 thus starting the shaft 176 fore. full rotstion, lowers this cross-head 190 into position to bring thetongues 196 in opposing relation adjacent opposite extension portions201. Furthermore, rotation of' this shaft 176 brings cam portion 202 tocoect with intermedlate rod 293, thus shifting such rod relatively tothe hars 191 between which bers 181 the rod 203 is guided, so that thereis e, rocking of the angle levers 192, 19d, to swing `the tongues 196toward each other and thus re-establish the crease lines for folding inthe end closure extensions, which lines have been given rigidity by thecoating operation. The container entering element is indicated at 208',being secured to the lower end of rod 203, and this element cooperateswith the v-tongues 19d in re-establishing the crease lines hy interiorlysupporting the container wells. This ineens there is thus initiated apartial collapse extension 204 of the container 138.

The completion of the shaft rotation after this initiating of theextension collapse results in so disposing the cams 180, 202, that theshorter radius portion is downward and the springs 185 may eect recoveryor ascent of the breaker device clear of the container 136 so that theattendent may grasp handle 205 and slide the rod 200 in bearings 206 tothe right, thus shifting the ex tension re-established fold linecontainer 136 clear from its position under the breaker to e. secondposition along the platform 198. As so disposed, the shaft 200 may berocked to clear the nger 199 from the line of the platform 198 end therod 200 shifted to the left to the initial position.

Filler The shaft 176 is shown as equipped with cam 207 (Figs. 22, 23)coacting with rod 208 as directed by guide 209. This rod 208 carries xedcollar 210 against which acts spring 211 for urging cylinder 212downward in reservoir 213 about tubular discharge tube 214. Thiscylinder 212 is equipped at its lower region with check valve 215 freelyopening for flow of milk into the cylinder 214 and closing againstoutflow. A measured volume of milk is thus charged into the res- I nommaervoir container 213 by way of pipe 214 for manitaining a level of suchliquid therein. The ascent of this cylinder 212 lifts the measuredquantity of liquid in the cylinder 212 and allows such to descend to berefllled with its major quantity of liquid in this filler for secondcharging operation.

The handle 205 is again given the single cycle of operation for shiftingthe charged container 136 from the lling station by the action of finger216 similar to the finger' 199.

Coating melting ,for final scalino The shaft 176 carries cam 217 (Figs.22, 24) effective to depress rod 213 as directed by guide 219. This rod218 has xed thereon collar 220 with which coacts compression spring 221normally holding this rod 213 elevated against the cam 217. This rod 218in its lower region carries jacketed electric resistance energized byelectric current connection thereto (not shown). 'li'his resistanceprovides heating element 222 as a warmer for softening the adhesive ascoating the extension 4204i of the container 136. This softening orpartial melting of the parailln coating on the container 136 bringsabout a condition so that the operator after this heater 222 hasascended, may again operate this rod 200 through the handle 205 forcausing` finger 223, similar to the `finger 199, to shift from thirdstation to fourth station on the `platform. 198. At this position vtheremay be ilnal closing operation mechanically or,as herein disclosed, bythe operator, and the operators action at this station is shown as inorder. The extensions are thus brought into fully collapsed and primarysealing position (Fig. 42) with the softened paran creating adhesivecondition so that vthe full closure'of the vessel is thus attained. Fromthis fourth station the closed con'tainer may be abutted by finger 224on the shaft 200 for shifting to a fifth station,or additional station.4

A Final sealing closure The shaft 176 is provided with cam 225, hereinshown as of general eccentric form (Figs. 22, 23). Coacting with thiscam 225 is roller 226 on lever 227 having hired fulcrum 228. Dependingarm of this lever 227 has rod 229 pivoted therefrom surrounded bycompression spring 230 tending normally to tilt this lever to hold theroller 22d against the cam 225. This rod 229, as directed by the frame184 through which it extends, terminates in toggle 231, upper link ofwhich is mounted in bracket 232 carried by the frame 184. The lower linkof this toggle is confinedv by bracket 233 with lever extension 234therefrom in oppostion to abutment 235 carried by the frame 184.

This abutment 235 and extension 234 forma pair of opposing jaws whichreceive therebetween upwardly extending rib 236 of the collapsedextension or upper end closure for the bottle 136.

Accordingly, in the rotation of the cam 225, the

lever 227 is rocked against the resistance of spring 230 for effectingthrough the toggle 231 shifting of the movable jaw 234 toward theabutment 235 for squeezing the rib or tongue 236 therebetween in a finalclamp holding. One of these Jaws, herein shown as the movable jaw 234,is provided with stitcher device or stapling machine for taking wirefrom spool 237 and by means of plunger 238 operated from mechanismmovable relatively to the Jaw 234, eect stapling operation through theextensloni236` in forming stitch 239 (Fig. 43). I

This stapling orl wire stitching device may be of a general form, say asshown in Patent 1,1l3,879,

' l Uperation It is accordingly seen that hereunder there may beeffected from the receiving of knockdown containers, the' preparation ofsuch containers for sealing and sealing into the contain-h vers of a'.substance herein shown as fresh to be supplied to the intimate consumer.

treadle 9 for opening up the flat blank 27' into tubular form andthrusting such blanlr down upon the block 28, there to have end aps 59glued and sealed thereagainst. Such container 106 is removed from theblock 22 as another tube is charged thereon. The removed container isplaced in pocket 102 of conveyor 103 conducted for a drying period andthen automatically discharged into the coating machine, there to havepar dipping, then conveyed by conveyor 141 into proximity to the stationof the second operm ator, where the article may be in the maintainedsynchronism of the machines against excessive accumulation.

This operator may locate the completed milk bottle container in positionfor breaking of the coating rigidity to reestablish the initial creasingor end closure collapsing condition. The procession or sequence of thesecontainers in these step by step operations brings this collapsedextension container into position for charging; then to have adhesivecondition producing melting down of the coating; primary sealing of theilnal end closure; then full or complete sealing; and even stitching, ifsuch be desired, with the article as thus completely sealed and in thecontainer shifted further along the platform 198 for deposit in cartonsor other means of delivering to the place of storage or transit.
